【摘要】 对日本落叶松采穗圃的经营管理研究结果表明：以日本落叶松采穗圃母株定干１４０ｃｍ 、骨干枝长度４ ～６ｃｍ 、４ 月中旬采条最有利于母株生产出更多的优良穗条。母株不同部位的插条，其生根率无明显差异，但母株上部插条的扦插苗高度显著高于中下部插条的扦插苗高度更多还原

【Abstract】 Results of the research on scion nursery management of L.kuernpferi Sieb.et Zucc showed the fixed trunk length of parent trees in the scion nursery of L.kaernpfert Sieb.et Zucc was 140cm,the length of the main branch is 4-6cm.Collecting scions in the middle of April would be beneficial to parent trees to produce more and superior scions.Scions from different part of a parent tree had no effect on rooting rate,but height of saplings from scions of the upper part of a parent tree was much higher than that from the middle and lower part of the tree.更多还原
